Addition to 365,998. [Class 80 (ii).] The invention described in the parent Specification is modified by replacing the teeth jaws or the like by co-operating friction-clutch members of such a nature that under torqueloading they resist or prevent disengagement. In the form shown, the gears 11, 58 are adapted to be clutched to the driven shaft 52, and the gear 55 to the countershaft 51, by clutches having external cones 65, 66, 67 secured to the respective gears and internal parts formed as nuts 62, 63, 64 mounted on screwed portions of the shafts. The nuts 62, 63 are rotatable to engage the corresponding cones by longitudinal movement of keys 69, Fig. 3, which carry inclined projections 69a, 69b engaging inclined slots in the nuts. The nut 64 is operated by a similar key 72. The keys 69, 72 are respectively connected to collars 70, 73 actuated by forks 71, 74. For the lowest speed, all the clutches are disengaged as shown and the gear 53 splined on lay shaft 51 is slid into engagement with gear 54 on the driven shaft 52. For second speed, gear 53 is slid to idling position and clutch 67 is engaged, drive being transmitted from driving shaft 9 through the gears 11, 50, 55, 56. For third speed, clutch 66 is engaged by sliding fork 71 to the right, and clutch 67 is disengaged, drive being transmitted through gears 11, 50, 57, 58. For solid drive, the fork 71 is slid to the left to engage clutch 65 to transmit drive from the driving-gear 11 to the driven shaft 52. When changing gear, the clutch in engagement is disengaged by rotating the driving shaft 9 slightly backwards by the brake 38 and drum 4 as described in the parent Specification. Specifications 273,382, [Class 80 (ii), Gearing, Variable-speed &c.], and 374,547 are referred to.

Filed: 1957-02-19
Abstract: <PICT:0810071/IV (a)/1> Iso-olefins containing 4 to 7 carbon atoms are polymerized using a catalyst slurry obtained by mixing a finely-divided aluminium halide catalyst with a hydrocarbon diluent which diluent prior to mixing with the catalyst is passed through a bed of solid desiccant which is periodically regenerated by heating with a substantially dry hydrocarbon diluent in the form of superheated vapours at a temperature above 100 DEG  C.  The regeneration is preferably effected in a direction countercurrent to normal diluent flow.  The isolefin exemplified is isobutylene, the desiccant alumina gel and the hydrocarbon diluent hexane or commercial hexane.  In the diagram commercial hexane in storage tank 10 is pumped through one or both driers 20 and 30 containing a bed 23 of a finelydivided desiccant, then through beds of coarse aluminium chloride in tanks 40 and 50, filtered in tanks 60 and 70 through beds of coarse bauxite, and stored in tank 151. The desiccant in driers 20 and 30 is regenerated by pumping a portion of the dry hexane from tank 151, through superheater 171, through pipe 159 into tank 20 from where it is withdrawn by pipe 162, from which after the removal of the water removed from the desiccant 23, it is returned to tank 10. The remainder of the dry hexane in tank 151, is mixed with the catalyst in tank 86, and passed via cooler 93 into the polymerization reactor 100 from which the polymer slurry is withdrawn via pipe 112.

Abstract: 744,313. Making composite tubes. CHESTERFIELD TUBE CO., Ltd., and UNITED STEEL CO'S., Ltd. Feb. 25, 1954 [March 2, 1953], No. 5775/53. Classes 83 (2) and 83 (4). Extruding.-A tubular junction piece between tubular members of austenitic and ferritic steel respectively is made by inserting two heated slugs 1, 2 of the respective steels, assembled face to face and sealed together at their exposed mating surfaces, in a die or container 4 and extruding them by a plunger 6 into tubular form thereby to force the trailing slug 2, Fig. 2, into the leading slug 1 and thus produce a joint in which a tapering length of one steel surrounds a complementary tapering length of the other steel. The slug 1 is of austenitic steel containing 18 per cent chromium, 12 per cent nickel 1 per cent niobium and 0.1 per cent carbon; the slug 2 is of ferritic steel containing 2.25 per cent chromium, 1 per cent molybdenum and 0.1 per cent carbon. The slugs are welded together at 3 to prevent oxidation at their contacting surfaces and are heated to 2150‹ F. The slugs are then extruded between the outlet of the die 4 and a mandrel 5 to form a tubular junction piece which may be drawn down to a smaller wall thickness and then machined inside and outside to the desired diameters. This junction piece is butt welded in position between austenitic and ferritic steel tubes 22, 23, Fig. 5 (not shown). In order to prevent migration of carbon, a barrier layer of nickel, applied as an electrolytic coating or as a thin sheet, is disposed between the two slugs. A number of pairs of austenitic and ferritic steel slugs 1, 2, Fig. 6, welded together at 3 as a unit or in pairs, may be extruded in one operation to form a tube which is subsequently cut into individual junction pieces. These slugs are solid and are pierced by a piercing mandrel 10 before extruding. In another embodiment, Fig. 7, a pair of slugs 1, 2 are extruded rearwardly by a punch 11 to form a composite closed-ended cylinder which is subsequently drawn through dies 17, 18, Fig. 10 (not shown), and the closed end is then removed. Punch guides 14, 15 and an ejector 13 are provided.

Abstract: 1,091,468. Photo-electric thickness measurement. JOHNSON MATTHEY & CO. Ltd. May 11, 1966 [Feb. 11, 1965], No. 5942/65. Heading G1A. The thickness of a thin film upon a substrate is determined by a beta-ray back-scatter measurement. In Fig. 1 a source of beta-rays - krypton 85 - is contained in a cylinder 5 having a nickel foil window in its upper end through which betarays pass to impinge upon a test sample supported on the casing 7. Plate 6 having the aperture 5 is one of a number which have various aperture sizes. Rays scattered back from the sample through the aperture impinge upon a scintillation screen 3: the light impulses being detected by a photo-multiplier 1 whose output passes to an amplifying, counting and timing mechanism giving a visual display, the reading of which is decoded into thickness measurements with the aid of calibration charts. The upper casing 7 in reality, but shown differently in the drawings allows the krypton cylinder 5 to rest upon an aluminium foil screen 3A covering the scintillation screen 3. The amount of back-scatter is related to the atomic number of the reflecting material and the coating and substrate substances must therefore differ in their atomic number.
